T 0 all whom it may COILFGMI'.

Be it known that 'I, ARTHUR R. HM'ENER, a citizen of the United States, residing at \Vayland, in the county of Middlesex and State of Massachusetts. have invented new and useful Improvements in Shipping-Case- Riveting Machines. of which the following is a specification.

This invention relates to machines tor attaching together by means of metallic fasteners, preferably bifurcated rivets, the closing flaps of a shipping case, these cases being made-of 'fibrc, pasteboa-nd or the like.

The object of the invention is to'provide a simple, convenient and easily operated machine whereby the flaps of a shipping case ay be firmly connected together by metallic fasteners such as rivets.

The invention consists in the combination and arrangement of parts set forth in the tol loW-ing specification and particularly pointed out in the claims.

Referring to the drawings:

Figure 1 is a side elevation of a portion of a riveting machine of well known construction ivith my improved attachment for riveting shipping cases shown in connection therewith, a shipping case being shown in section in position to be operated upon by said machine.

Fig. 2 is a sectional plan taken on line 2?2, Fig. 1, the same being broken away to save space in the drawings.

3 is a a roiit elevation of the head of a riveting machine such as is shown Fi 1, together with the work support and \viti a shipping case shown in position for riveting and positioned relatively to the improved attachment which forms a part of this invention.

Fig. 4 is a plan view of a shipping case after the same has been riveted by the machine of this invention.

In the drawings 5 is the lruinc ol the nun china. 6 the head, T the driver. the rivet holder, 9 the work support. i a screw by means of which the work support may be raised and lmvereddhcsaid work support heiug provided in its upper Face with balls 11 uponuhichthcshippiugvaso ii rests during the riveting opcruLif-n. .iu anvil 13 is provid ed which is fastened to a horizontally disposed anvil blade ll. The from end of the anvil blade ll is fastened lo :1 bra ket 15. said bracket being mounted to rotate upon a stud 16 constituting a pivot. The stud 16 passes upwardly from the bracket through a sleeve which is fastened by means of a nut 18 having screw-threaded engagement with the upper end of the stud 16 to a right angle support 19 which is fastened by screws 20 tothe head of the machine. The lower end of the bracket 15 is bent ,to form a 'V 21, said V having two legs 22 and 23 the leg 23 ha ng a recess 24- therein adapted to receive one flap '25 of the case 12. Another flap 26 is adapted to project into a recess 27 formed by the legs -22 and 23 of the V shaped portion of the bracket. The front end of the anvil blade 14: is fastened to the underside of the portion of the leg 23 which is located beneath the recess 24. will, therefore, be seen that the lower portion of the bracket 15 constitutes a foot which not only supports the front end of the anvil blade, but also provides means whereby the flaps and 26 may be guided during the riveting operations. he rear end of the anvil blade l l is adapted to be supported upon a stationary bracket 28 which is fastened to the frame of the machine, see Figs. 1 and 2. The arm 14 is looked in the position illustrated in Fig. 2. that is in operative position, by means of a pin 29 which is fastened to an arm 30, said arm being pivoted at 31 to the underside of: the horizontal portion of the bracket 28.

The pin 29 projects upwardly from .the arm through a slot '32 in the horizontal portion of said stationary bracket 2-8 and into a notch 33 provided in the rear edge of the anvil blade ll. Another pin fast to said stationary bracket 28 forms a stop With which theanv-il blade 14.- ,contacts when in operative position. A portion 35 of the rear edge of the anvil blade is inclined for a purpose hereinafter described. The arm 3G is held in the position illustrated in Fig 2 by a spring 36, one end of which is fastened to a. pin 37 on said arm. the other end of which is *fa-sten'ed to a pin fast. to the head of the machine. A COIIVOXlj' curved plate 39 has a shank 40 thereon which extends through the free end of the arm 3 and is held in said arm by a set screw 41. The object of the mechanism just described is to provide a means for locking the pivoted anvil blade in operative position, which means is also adapted to be operated by the contact therewith of the case being riveted to unlock the anvil blade and allow the same to be swung upon its pivot to one side and thus allow the case to be removed therefrom after the riveting operations have been performed.

It will be noted that the anvil is located upon the anvil blade intermediate the pivotal stud 16 adjacent the front end of the anvil blade and the stationary supporting bracket 28 which is adapted to support the rear end of the anvil blade.

The general operation of the mechanism hereinbefore specifically described is as follows: The case 12 is placed upon the work support 9 with the flap- 25 projecting into the recess 24 and the flap 26 projecting into the recess 27. With the anvil blade in the position illustrated in Fig. 2 the machine is then operated to drive a rivet 42 through the flaps 25 and 26 and clinch the same in the usual manner upon the anvil 13. The operator then moves the case along the anvil blade 14 toward the rear end thereof the correct distance and then operates the machine to drive successively rivets 43, 44 and 45 through the flaps 25 and 26. After the last rivet 4 3 has been driven, the operator moves the case a little further toward the rear of the anvil blade, thus bringing one end of said case into contact with the plate 39- which causes the arm 30 to be swung upon its pivot in the direction of the arrow a, Fig. 2. thus the pin 29 will move out of the notch 33 and the anvil blade will then be free to be swung in the direction of the arrow 7), Fig. 2, until it is brought to a position where the case can be slid oil of the anvil blade. The anvil blade is then swung back in a direction reverse to the arrow 6, the inclined edge 35 will strike the pin 29 and will swing the arm 30 upon its pivot 31 in the direction of the arrow a until the anvil blade engages the stop pin 34, whereupon the pin 29 will be caused to enter the notch 33 by the action of the spring 36 and the parts are then in position for another case to be operated upon.

I claim:
